What does the lack of a magnetic field on Mars indicate about its internal composition?

- There are two main types of magnets: Permanent magnets and electromagnets. Permanent magnets are always magnetized. Electromagnets are magnetized due to electricity and can be turned on and off.
- All magnets have two poles: A south pole and a north pole. Opposite poles attract. Like poles repel.
- Earth's magnetic poles do not line up with the geographic poles. The magnetic poles wander around the globe a little every year.
- Earth is surrounded by a magnetic field called the magnetosphere. This deflects charged particles, trapping them in the Van Allen Belt, and creating the auroras with others.
- Earth's magnetic poles reverse direction. This last happened 700,000 years ago. Over the last 10 million years, it has happened about every 250,000 years.
- Earth's magnetic pole reversals are recorded in rocks in the ocean floor. The magnetic orientation is frozen when the rock cools; as the rocks slowly move away from ocean ridges, magnetic striping is created. This is a key piece of evidence for plate tectonics.
- The Dynamo theory states that Earth's magnetic field is due to the circulation of iron in the outer core. Movement of conductive materials can create electromagnetism

What does the magnetic flux per unit area indicate?
the strength of a magnetic field
What occurs if the size of the magnet is change?
If the size of a magnet is changed, it can affect the overall strength of the magnetic field it produces. Generally, a larger magnet will have a stronger magnetic field, while a smaller magnet will have a weaker magnetic field. However, other factors such as the magnet's composition and shape can also influence the strength of the magnetic field.
The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
Does a superconductor expel a magnetic field?
As a superconducting material transitions into its superconducting state, it ejects internal magnetic fields. In that light, yes, a superconductor could be said to expel a magnetic field according to what is called the Meissner effect. A link can be found below.
Why is a magnetic field a vector quantity?
Magnetism is a force. Vector notation is required to indicate magnitude and direction of a force.
Do magnetic field lines close together indicate a weaker magnetic field?
no they are not
What does the magnetic flux per unit area indicate?
the strength of a magnetic field
What do bands of rock on the seafloor showing alternating magnetic orientation indicate about the earths magnetic field?
They indicate that the Earth's magnetic field has undergone shifting of the positions of it's poles several times in the past.
What is collected data about jupiters magnetic field and polar regions?
Data collected about Jupiter's magnetic field and polar regions provides valuable insights into the planet's composition and dynamics. It helps scientists understand the interaction between Jupiter's magnetic field and its atmosphere, as well as the formation and behavior of its auroras. Additionally, studying Jupiter's magnetic field and polar regions can provide information about the planet's internal structure and its magnetic interactions with its moons.
What does a magnetic field around a planet indicate?
That it has a metal core.
A device that uses the Earth's magnetic field to indicate which way North is?
That is called a magnetic compass.
What does the presence of a magnetic field on Earth compared with other terrestrial plants indicate?
Plants don't have a significant magnetic field. Perhaps you mean "planets"?
How can you tell a planet's composition?
The density can be computed from the volume and gravitational pull (mass). This will usually indicate the types of elements and compounds that make up the planet. The magnetic field gives a clue to the type of core.
Does the earth's magnetic field give information on the earth's interior composition?
The earth has electric currents in its structure, that create magnetic fields.
Composition of an electrormagnetic wave?
An electromagnetic wave is composed of two parts. One is the magnetic field and the other is the electric field.
What would indicate an magnetic field?
You can detect it by watching a compass needle, if that's what you mean.
A device that uses the Earths magnetic field to indicate witch way north is?
A compass.
